Which process is shown in the plant cell below?
A= cell growth
B= cell reproduction
C= metamorphosis
D= photosynthesis
The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.
What is cell reproduction?Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.
Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.
Therefore, The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.

A _____ model places Earth at the center of the solar system, with the Sun and planets revolving around Earth. A. scale B. geocentric C. heliocentric
Answer:
B. Geocentric
Explanation:
Geo means Earth, and centric means "in the center". So a geocentric model of the solar system would mean the Earth were at the center of the solar system, with the Sun and planets revolving around the Earth.
Answer:
geocentric model
In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth.

2. In the example of the white and brown mice, vultures will prey on both colors of mice. However, in
the desert environment, the brown mice are better able to hide from their predators and have an
advantageous trait. What will happen to the color of mice over time?
Answer:
The brown color of mice would become more common in the population of the mice in the desert overtime
Explanation:
In the mice population, since the environment favors the individuals with brown fur color over individuals with white fur color, as it makes them better able to escape from predatory vultures, white mice gets eaten more often. With time, the population of white mice reduces while that of brown mice increases.
Overtime, brown mice leaves more offspring with its trait compared to white mice. As a result of this, the color mice that would be more common in the desert environment would be mainly brown colored mice, while white mice would be few.

Which component of a DNA synthesis reaction determines the exact nucleotide sequence of the product?
Answer:
The complementary base pairing between incoming nucleotides and the DNA template
Explanation:
In a DNA synthesis reaction, the exact nucleotide sequence of the product is basically determined by both the DNA template from which a new strand is made and the incoming new nucleotides that makes up the new DNA strands. A complementary base Paris between these two gives the nucleotide sequence of the product.
Which statement is true of DNA polymerase?
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.

interphase, prophase, and metaphase
mitosis, meiosis, and the formation of the final protein
transcription, mitosis, and DNA replication
Answer:
A.
Explanation:
The cells control gene expression at transcription, translation, and the formation of the final protein.
What do you mean by gene expression?Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
